Winter - Nature’s Cold Storage
For birds and other animals with good natural insulation, winter provides a striking benefit as they scavenge. Bacteria function very slowly or not at all in the cold, preventing dead bodies from rotting. In northern latitudes, ravens and other scavenging birds take advantage of winter's cold storage. When a caribou, moose, or deer dies in Canada, Alaska, or other cold place in the winter, it's available to be eaten for months. Bacteria must wait until spring warms the carcass before they can begin to consume it.
